"....if the NewCo spin off was to occur it should have been done after success of the Assure trial and not before!!,,,,,,,I dont have a clue what I own or what it may be valued at...."

In May of 2016, ZEN did a private placement at $1.00 US a share.

In June of 2016, they said the Enterprise Value est. was $125 MM, with Shares Outstanding = 125.2 MM.

So the math is consistent on that.  They valued it at $125 MM with 125 MM shares = $1.00 PP.

Now, the Enterprise Value est. is $350 to $375MM USD ($2.50 to $3.00 USD/share) est. Shares Outstanding is 125.2 MM.

So clearly that's where they value it.  They must be trying to get $2.50 to $3.00 US in a private placement.  You can't very well value it at  $2.50 to $3.00 and do a PP for eg. $1.50.

I assume they are also trying to establish a value for an IPO.

Success of the ASSURE trial?  Huh? Say what? 

It wouldn't have made sense to do the NewCo spinoff after ASSURE.  I view it as having a viable company remaining (NewCo) in case ASSURE was a total failure and they decided to abandon RVX-208.  If ASSURE was a success, no need to spin off.  If ASSURE was a failure, too late to spin off.
